To whom z'tmay concern.'

Be 1t known that I, GEORGES HAARNAGELL,

acit-izen of'France, and a resident of Paris,

' rack side,

said groove is fixed a guide 1 profiled in such y a way thatit Department of Seine, France, have invented some new and useful Improvements in Slid` ing Windows for Vehicle Doors, of which the following is a specification.

The main object of the invention is to provide a coach door wherein the glass Square is guided in a Way absolutely excluding anyv vibration of the same, means being provided to permit easy xing of the glass in any desired position of the same. l

I attain these objects by providing grooves in the door frame for the glass squares, said grooves being trimmed with soft material,

preferably velvet, along the edges' of .the glass, said means excluding, together with suitable rubber trimming rovided on the crossbars, any vibration o? the glass.. In order to fix-the' latter in any desired 'position of the same, a toothed rack is provided along the one border of the aperture for the glass, and a toothed lever is arranged piv- Votally on the glass, the said lever engaging normally b action of al spring into the teeth of said rac and permittlng upon being depressed, the adjustment of the glass to anyv desired height. The pivot for the said lever is provided preferably on a second lever iixed to the glass and supporting the said The Figs. c, 7 and ashew, in difierenv views additional means consisting in a pres-y sure cushion for intermediate glassesor' for glasses of larger dimensions.l

Fig. 9 is a View ofv a detail.

{Referring to Figs.. 1, 3 and 4,l thev coachA door is provided with a groove F and into presents a wing 2 projectin a little loutward rack-3 is attac ed. v -v In the guide 1 is adjusted and may be equally fixed a second guide 4 with its inner tirely freed from the lines of Figs. *Y

;'to this projection atoot ed side entirely'covered by velvet v5 orV the like,

this velvet forming upon its whole length f a cushion, wherein slides with the sufiicient degree of friction the frame E ofthe glass square G. Similar guides not provided with racks are disposed in aguide in the opposite y side of the door, said guides being shown in Fig. 5. The lower part of the door is also provided with grooves tted with velvets, in a way that the glass squarev is conveniently guided along its whole trajectory. The

teeth of the `rack do not ro]ect from the border .B of the (groove 'and said teeth are xncluied upwar l ,which is'of importance to secure a proper engagement of'the knob of the catches P fixed upon ythe frame E of the glass square.

These catches are and P, the part P being fixed upon one'r side of the frame E of the glass, the said frame formed of twoparts P' bein of channel formation asclearly shown in Figure 4.' The. art P is movable around a pivot 6 andten s continuously to engage' therack 3 by the action of the spring 7 1nterposed between the levers of the catches.

It will be noted that the arts P and P are substantially arallel wit ,the glass and are at oneside t ereof where they'canbe convenientl reached and actuated.

The catc es are, as shown in Fig. 3,"engroove, their engagment with the rack belng very vetlicient cause the inclination of the teethprevents the tooth of the member P from becomin casually disengaged from its retaining rac and vto scratch the rack'in case of disengage` ment occasioned by the weight of the'glassl and by vibrations or the like.

VIt will be understood, thatin order to completely lower the glass or to arrange th same in an intermediate position it will suiiice to act upon the movable part P of the catchv to uncouple its tooth from the rack. (The opening and the closing of thel glass may beeifected easi1y,`without appreciable effort, and with two or'fthree fingers, because,

.the invention is destinedI to be usedparticu- 1 larly in combination with the U. S. A. Patf ent No. 1,305,3'5`6L-)1 This device is shown anew in Fig. 2 .though withoutv necessity for understanding of the function of the parts 'forming subject matter of the ypresent invention. i

In order to avoid the vibrations of Athe .glass during the movement of the vehicle and to increase the guidance of the glass square during its displacements, the border of the crossbar T of the centre of the door is provided with a tongue C of rubber, (more especially to be used. for glasses of large dimensions, intermediate glasses of auto ve-4 hicles, of tramways'and the like. In such case two such tongues or a plurality of them may be employed.)

The tongue C 1s arranged, as shown in Fig. 9 in a groove 8 and extends over the Whole Width of the glass square. p

According to Figs. 6-8 a press-cushion is shown in them destined to replace the tongue C especially in case of glasses of large dimensions, intermediate glasses of auto vehicles, of tramways and the like. In such case two tongues or a plurality of them may be employed.

This press cushion consists of a bar 9` upon which is fixed adjustably, by means of screws 10 and guides 11, an angle piece l2 supporting in a groove 13 a cushion 14 of india rubber chamfered to the shape of a knob in order to ensurel a glass.l

perfect contact with the Legales 'Having now described the nature of my invention, what I claim, is:

A vehicle door having a Window opening, channel guides in opposite sides of said opening, one of said guides being provided on one side With a rack bar the teeth of which overlie the vouter edge thereof, a glass pane having a frame forming a channel member on one side edge of the lass and arranged to operate in the said guide member, and a catch comprising a relatively iixed member secured directly to one side of the said frame, said fixed member being arranged substantially parallel With the glass, a second member pivotally connected to said relatively fixed member and having a tooth at its upper side to engage with any of the teeth of the rack to secure said glass in adjustable position, and a spring arranged between said members and active to normally hold the pivoted member in engaged position, said pivoted member being also ar-y ranged substantially parallel with the glass. In witness whereof I ax my signature. yGrEORGllS HAARNAGELL.
